RING-VA LVE.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed December 26, 1906. Serial No. 849,403.

To all whom it may concern:

Be it known that I, FREDRICK WILLIAM RooLEn, a citizen of the United States of America, residing at Vienna, Austria-Hungary, have invented certain new and useful improvements in Ring-Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art t9 which it appertains to make and use the same, reference being had to the accompanying dgawings, and to letters ori'igures of'reference marked thereon, which 'form a part of this specification.

Myinvention relates to ring valves for blowing engines, umps, compressors and the like, and has l dr its object to construct such valve of flexible material having one or more connected discontinuous valve rings and one or more continuous rings all made of a single piece, as will hereinafter be more fully described and claimed.

hel'erring to the drawings, in which like parts are similarly designatedFigure 1 is a double ring valve, one of the rings being double-split and the other continuous; Fig. 2

is a triple ring valve, having one continuous and two double-split rings; Fig. 3 shows an outer continuous ring and two central, triplesplit rings. .Fig. his a diametrical section through such a valve and its mounting, and i ig. 5 shows the limit ring therefor; Figs. 6 and 7 show, respectively, a plan of a continuous ring valve, having a central double-split ring, and a diametrical section through the valve and mounting. Fig. 8 is a diametrical I section through another form of valve Fig. 9,

a plan view 01' the seat; Fig. 10 a plan of the valve, and Fig. 11 a plan of the limit ring. Fig. 12 is a section showing a dished form oi valve. Fig. 13 is a transverse section ollan Fig. 14 is a plan of its seat. 16 is a plan of the limit ring.

The invention comprises a valve consisting of one on more rings transversely or substantially transversely cut or split at several points of the periphery and being connected to one or more complete rings. V-z'hether there be but a single splitring or several split-rings, united to one or. more full rings,

. the whole structure is made-of a single piece of spring sheet metal or other suitable material and secured to the valve seat at the center of it. Such a valve unites the advantages of a l lap valve and a ring valveawithout Fig. is a plan. of the valve and Fig.

rather heavy sheet spring metal.

the disadvantages of these two forms of well known valves, as all the closing parts of the valve follow circular lines and are free from any rubbing or sliding movement. The concentric parts of the valve are spaced from one another radially so that the lluid controlled can pass between those parts and the valve seat. v

In Fig. 1 I have shown a valve that has two concentric rings 1) and w. The inner one p is made as a discontinuous ring the two ring-halves of which are united by a diametrical arm 7* the ring loeim split or out, or made discontinuous on eac side of the arm 1- at g q, the cuts being inclined to the diamet'rical arm 1*. ring are connected by portions t, t to the outer ring w, which is made as a continuous The valve late 1) w, is secured to the center of the va ve seat by a bolt passed through the center at 8. Such a ring valve operates ,very well 'even' when made of In this valve the ends 2. t of the inner double splitring p 13 move similarly and cause the outer ring w when moving to and from its seat, to move parallel or substantially parallel thereto, with a very'small extent of rotation, so that therewill be nolfrihtion on the seat. A small pressure suffices to open. or lift this valve, as the lever arm of the force tending to lift the valve is comparativel large. The

arm 1' partakes somewhat of t e movement of the valve.

In Fig. 2 I have shown a third continuous ring w, surrounding and united to the valve shown in Fig. 1, and. in which the widths of the rings or the radial distance apart of the ring seats, or both, may increaselrom the w center outward, In which cases the lift of the outer rm to only,

will require to be limited by a limit plhte. I

Inthe foregoing Figs, 1 and 2, the outlinesf oi' the openings in the valve seats under the 'rmg are shown in dotted lines.

*3 shows a valve plate with three conc'entric"',in.gs, 26, 31, 35, the inner two consisting'o'l: three equal sections sep a'ratcd from each other by splits 127 and 33, and being connected to the outer continuous ring by connecting pieces 36 all formed of a single piece or" sheet metal. This valve is shown with its seat 39 in Fig. i, a Washer 40 distancing the cushioning ring 38 (shown in plan in Fig. 5) and having above the cushioning ring a limiting ring 37 Washer 54 and above Fig. 6 is a plan, and Fig.

Fig. 1, carryin a leather or other packing ring 42 securcdhetween the outer continuous ring 34 and the ring 41 seating cessed opening through the va ve'seat 44.

Rivets 42 secure the parts 34 42 and 4-1 toether, While the yielding limit ring 43 limits the lift of the valve.

The valve shown in plan in Fig. 10 comprises a central two-split ring 45, split at 46 and made narrower at the points 64 to in crease the flexibility and connected at 4:7 to a continuous ring 48which is connected at points ll) with-the outer ring 49. Such a valve is designed for use as a suction valve, and its mount is shown in Fig. 8, the seat 50 of which is mounted in a cy inder head 65, the seat 61 being and 52 being openings therethrou h and 57, {58, 59'and 60 the raised edges of t 656 open- IHOS.

' lhe cushioning ring 53, shown in land in 11, is distanced from the va ve by the cushioning ring is a rigid limiting ring 55 having ockets 62 diametrically apart to receive coil springs 63 I to. aid in closing the valve, said springs tak- 'ment molten overcome by iiig over lugs on-the valve; prevents the parts from rotating.

"The loadingof the valve by springs 63 is not always necessary, but is advantageous in using very large valves with several rings, or very uick acting valves, and this requiredishing the valve so that when .it is secured to its seat 61 it will have a certain pressure thereon.-

ln Fig.

" .12 such a dished form of valve is shown de- .for. closing ports 51, 52

tached lrom its seat and not under tension. he ring 45 may beg-round out at the narrowest points 64 in order to increase the flexibility. i

For certain purposes, i or example in valves having a large lift, it is of advantage to so arran e'the valves, especially when additiona y loaded by when in closing position have a dished form, as shown in Fig. 12.

The valve shown in Fig. 15, like the one shown in Fig. 10 comprises a central ring 45 split at two points 46 The segments of the ring l5 are, near the points 46, of greater Width than at their middle at 64, and they are also ground out on the upper face to reduce the thickness at the points 64, thereby increasing the flexibility of the ring. At 47' said ring is connected I 48, wh';h latter at 40 is connected toan outer, likewise continuous, ring 49. In. this valve the three rings 49, 48 and 45 serve and 66 respectively in. the valve seat 50. In Figs. 13 and 14: the

' edges of said ports are designated '57, 58,

The rings before being mounted on the valve seat 61 has a dished form similar to that shown in Fig. 12. The parts 55, is 53 and 54: are prevented from rotation by a pin 56 taking through themginto the valve seat.
